The common light sources for outdoor solar street lights today include incandescent, halogen and LED lamps.
The incandescent lamp is the most common light source, which produces light by illuminating incandescence with an electric current.
It has a low cost and is easy to install, but incandescent lamps are not very energy efficient and a lot of energy is converted into heat, so they are also less environmentally friendly. Incandescent lamps usually last around 750-1000 hours, but they are prone to burning out and therefore have a short lifespan.
A halogen lamp is also a common light source that produces light by placing a type of halide into a vacuum glass tube and illuminating the halide with an electric current. Halogen lamps have a longer life than incandescent lamps, usually around 2000 hours. However, the spectrum produced by halogen lamps has some color distortion and does not fully simulate natural light.
Compared to incandescent and halogen lamps, LED lamps are more energy efficient and have a longer lifespan. LED lamps are therefore the best source of light for outdoor solar street lighting today.
Advantages of LED lights
- The LED light source is easy to install and can be installed directly.
- As the LED light source is one-way, the luminous effect is better than the ordinary lamp head, and the color rendering index is also high, no diffusion phenomenon will occur. And LED light decay of up to 3% a year, with a service life of up to 50,000 hours or more.
- LED light source is a low energy consumption product. Its power consumption is one-ninth of that of incandescent lamps and one-third of that of other light sources. This shows that it consumes very little energy and has a long life.
- LED light source also has many advantages, such as green, low glare, no radiation. Because of this, LED light source has become a necessary light source for outdoor solar street lights.
Overall, LED lights are currently the best light source for outdoor solar street lights. For example, SRESKY SSL-64 solar street light uses Osram’s imported lamp cores and 5700K LED, which provide a soft lighting atmosphere and high intensity lighting every night!
